Kerb Flo 5L Residual Herbicide

Kerb Flo 5L is a powerful, long-lasting residual herbicide designed for the control of annual and perennial grasses and a wide range of broad-leaved weeds. Containing propyzamide (400 g/L), it works by inhibiting root growth, providing soil-acting weed control that persists through the winter season and beyond.

Ideal for amenity grassland, ornamental plantings, industrial sites, hard surfaces, and around trees and shrubs, Kerb Flo is rainfast, effective in cold and damp conditions, and excels where glyphosate and contact herbicides fail. Trusted by local authorities, highways contractors, grounds maintenance teams, and estate managers, Kerb Flo ensures weed-free areas with minimal re-growth.
